Netflix also debuted new shows like Glow and Dear White People, new movies like Okta and comedy specials from Louis C.K., Tracy Morgan and Hasan Minhaj.

Not all the original series have worked out. Netflix has canceled a growing number of shows, including The Get Down, Sense8 and Girlboss.

Netflix also faces mounting competition from the tech industry. The list of companies investing in original content now includes Amazon(AMZN, Tech30), Apple(AAPL, Tech30), Snapchat(SNAP) and reportedly even Facebook(FB, Tech30), where Netflix CEO Reed Hastings serves on the board.

"The large-cap tech companies, especially Amazon, are investing heavily in original and licensed content around the world," Netflix said in its earnings release. "Creating a TV network is now as easy as creating an app, and investment is pouring into content production around the world."

"We are all co-pioneers of internet TV and, together, we are replacing linear TV," the company added.
